ABSTRACT
Objective To observe the clinical outcome of modified posterolateral approaches for the treatment of posterolateral tibial plateau fractures. Methods From January 2012 to January 2015,13 patients with posterolateral tibial plateau fractures were identified in the Second Hospital of Changzhou Affiliated to Nan?jing Medical University. All the posterolateral fractures were fixated with a plate. The knee function was evaluated at the last follow?up by the Hospital for Special Surgery( HSS) Score,and the occurrence of postoperative compli?cations were observed. Results Thirteen patients were followed up for an average of 14. 4 months,all patients obtained bony union. There were no significant differences regarding the mean HSS score among 3 months, 6 months and 1 year post?operation((71. 6±1. 5) points, (76. 4±1. 6) points, (83. 2±1. 1) points;P=0. 154) . There were no significant differences regarding the tibial plateau angle and posterior slope angle on radiograph?ies of inside and outsideamong immediate,6 and 12 months postoperation((83. 7±1. 7)°,(84. 3±1. 5)°,(85. 1 ±1. 4)°,(85. 4±1. 5)°;(7. 7±1. 5)°,(7. 7±1. 4)°,(7. 7±1. 3)°,(7. 6±1. 8)°;P=0. 223,0. 191). No com?plications associated with the approach were observed and there was no infection,no malunion or fixation failure either. Conclusion In the treatment of posterolateral tibial plateau fractures,the modified posterolateral approa?ches can result in excellent fracture reduction under direct visualization and allow for posterior buttress plating.
ABSTRACT
Objective To compare the clinic effect of the locking compression plate (LCP) fixation and the anatomical plate in treatment of high-energy distal tibial fractures. Methods The study involved 42 patients with high-energy distal tibial fractures treated between May 2003 and May 2009. The anatomical plate group included 24 patients ( 16 males and 8 females, at average age of 39 years), of whom there were 13 patients with type A fractures, five with type B and six with type C according to the AO/ASIF classification. The LCP group included 18 patients ( 15 males and 3 females, at average age of 40 years), of whom there were 11 patients with type A fractures, three with type B and four with type C according to the AO/ASIF classification. All the patients were followed up for 8-17 months. Their functional and radiographic outcomes were collected. The operation time, intra-operative blood loss, X-ray exposure, bone healing time, post-operative complications and therapeutic effects were compared between both groups. Mazur's criteria was used to evaluate the function of the ankle. Results The LCP group was followed up for average 11.6 months and the anatomical plate group for average 14.2 months, which showed fracture healing in all the patients. The bone graft in the anatomical plate group was used more frequently than the LCP group, while the X-ray exposure in the LCP group was much more than that in the anatomical plate group. The operation time, incision size, blood loss, postoperative complications and radiographic bone healing time in the LCP group were significantly less than those in the anatomical plate group. Conclusions Both the LCP and anatomical plate are effective methods for the high energy distal tibial fractures. LCP has advantages of less trauma, quick fracture healing and less complications, is consistent with the biomechanics of internal fixation and hence is an ideal method for the treatment of the high-energy tibial fractures.
